Prime Minister Benjamin Netanyahu told UN Secretary General Ban Ki-moon on Saturday that Israel has definitive evidence Hamas perpetrated the kidnapping of three Israeli teens and that Israel opposes a transfer of funds to Hamas in Gaza.

Netanyahu told Ki-Moon that “information in Israel’s hands unequivocally indicates that Hamas is responsible for the abduction of the youths, adding that this needs to be expressed in actions on the ground,” Netanyahu’s office said in a statement.

Coordinator Robert Serry denied the allegations, saying in a statement that he was approached by Palestinian Authority Prime Minister Rami Hamdallah about transferring funds from Qatar to pay Gaza salaries, but that he had made it clear he would only act if Israel was also amenable to the arrangement.

Channel 2 reported that Serry has been seeking relentlessly to transfer funds to Hamas in Gaza, to the immense displeasure of Liberman. Israel, the US and others designate the Islamic extremist Hamas, which is formally committed to the destruction of Israel, as a terrorist organization.

Netanyahu told Ban Ki-moon that Abbas needed to end the PA’s unity pact with Hamas, adding that Israel was “determined to defend itself in the face of the murderous terrorism directed against it.”

He cited the regional instability caused by Islamist militant groups in asserting Israel’s right to defend itself.

Israeli forces are embarked on a massive campaign to locate the three kidnapped boys while simultaneously destroying parts of the Hamas terror infrastructure in the West Bank.

The abduction has also cast doubt on Palestinian reconciliation efforts.

Palestinian Authority President Mahmoud Abbas has condemned the kidnapping and called for the safe return of the teens. Several senior PA officials have said that if Hamas was indeed behind the abductions, it will spell the end of reconciliation efforts.
